The car is now starting to overheat while driving it around, not just on an incline. The yellow indicator light is rarely coming on, but the engine fan will kick on and run harder and longer than it ever has in the past.
I took it to the dealer and they were able to replicate the fan and the indicator by driving it hard, but no codes are showing and they think the water pump and thermostat are working correctly.
They're holding it overnight to check some other things in the morning, but I think I'm going to get the car back with a bill and no resolution.
